nginx-0.3.57-RELEASE import
*) Feature: the $ssl_client_serial variable.
*) Bugfix: in the "!-e" operator of the "if" directive.
Thanks to Andrian Budanstov.
*) Bugfix: while a client certificate verification nginx did not send
to a client the required certificates information.
*) Bugfix: the $document_root variable did not support the variables in
the "root" directive.
